Five application scenarios of Bluetooth module

Bluetooth module , As an integrated Bluetooth wireless technology PCBA plate , It is mainly used for short-range wireless communication , It has become the backbone of the development of wireless transmission of the Internet of things . So what are the applications of Bluetooth module in real life ？ Follow Yibaite Let's have a look

One 、 Intelligent medical treatment

Current health and medical devices are usually wearable products or other small objects . adopt Bluetooth module , The health data collected in real time by the sensors of health medical devices will be transmitted to the computer equipped with Bluetooth module .MCU The processor will correct the value of the collected data . The correct value can be transferred to the file through the corresponding interface , The patient's health data can be transmitted to the screen through Bluetooth module . You can also use APP Be responsible for receiving and analyzing the received health data , Play the role of real-time monitoring of data .

Two 、 Bluetooth module Mesh Ad-hoc network Intelligent lighting

bluetooth Mesh The module builds the network and synchronizes with the cloud using a single control device , So as to simplify and effectively control all functions in the smart home system . In Bluetooth Mesh Intelligent lighting scheme , Users connect through mobile phones Mesh Any one in the network LED The lamp , You can control Mesh Any one or a group of lights in the network , Also on Mesh The Internet LED Light tubes are grouped , Dimming , Color adjustment , Scenario setting , bluetooth Mesh The architecture of can be extended to meet the office , factory , Industrial environment and even urban demand , And millions of nodes can be connected without failure .

3、 ... and 、 Smart wear

because Low power Bluetooth （BLE） Its low power consumption has been widely used in intelligent wearable terminals , Many smart devices rely on Bluetooth technology for wireless connection and data exchange , Most common examples ： Smart Bracelet 、 Smart necklace, etc , Because Bluetooth low-power technology can achieve the lowest power consumption of short-distance communication , Thus, the running time of wearable devices is greatly prolonged .

Four 、 bluetooth MAC Address scanning and printing

BLE Bluetooth module in Bluetooth MAC Act as the host in the address scanning printing solution ,

Scan peripheral devices

Filter by broadcast name

Screen out the equipment with the strongest peripheral signal

obtain MAC Address

obtain MAC After the address , Send data to label printer through serial port

The label printer prints a QR code that meets the requirements

Bluetooth in the form of QR code MAC Print out the address , Convenient Bluetooth products for Bluetooth MAC Address to read , Can effectively improve work efficiency .

5、 ... and 、 Intelligent door lock

In the application scenario of intelligent door lock , Using Bluetooth technology can meet the needs of different users and permissions , At the same time, ensure confidentiality . Install the Bluetooth module in the door lock , People can pass APP Read the Bluetooth information of the smart lock in real time , Then pair , Send an unlock request to the server , The server sends the unlocking command to the mobile phone , After the mobile phone receives the unlocking information , Send the command to the intelligent door lock through the Bluetooth module in the door lock , Then unlock . Very convenient 、 quick 、 Security .
